1921 | The ALSA driver fully supports the devfs extension. | ||
1922 | You should add lines below to your devfsd.conf file: | ||

1928 | Warning: These lines assume that you have the audio group in your system. | ||
1929 | Otherwise replace audio word with another group name (root for | ||
1930 | example). | ||
